Netanyahu reiterated his argument that the nuclear deal that has seen sanctions lifted against its regional rival Iran would require Israel to increase spending to maintain its military edge.

The influx of cash, he said, would allow Iran to further back proxy militants, including Israeli enemies Hezbollah.

Netanyahu said it would be important to “resist Iranian aggression in the region, which continues and might even accelerate given the amount of funds that they’re going to get with the lifting of sanctions.

“And the strongest way to stop Iranian aggression is to bolster America’s allies, first and foremost (of) which is Israel.”

He added that “we’re talking about a bigger package. But remember that even over a 10-year period, it pales in comparison to the enormous funds that Iran gets.”

The United States has unblocked an estimated USD 100 billion of Iranian assets held abroad and settled a long-running international dispute that will see Iran get USD 1.7 billion directly from Washington following the implementation of the nuclear deal.

Netanyahu, whose country is believed to be the sole nuclear power in the Middle East, though it has never declared it, strongly opposed the accord and labelled it a “historic mistake”.

His outspoken criticism, including in an address to the US Congress, led to troubled ties with the United States.

He has since scaled back his rhetoric and visited Washington in November as part of efforts to move past the rift.

A US delegation is due in Israel next week as part of discussions over the new military package, with the current agreement due to expire in 2017, Israeli newspaper Haaretz reported.

Israel’s total defence budget amounts to some USD 16 billion, excluding the US aid.

Netanyahu’s Davos appearance was dominated by issues such as Iran and Syria, but he briefly addressed the conflict with the Palestinians.
